This new title from Prashant Iyengar, published in 2013, is an exploration of Yogasana. Prashantji starts by reflecting on where in the Yoga Sutras Patanjali mentions asana and in what context. He then defines and discusses each of the 18 kriyas which constitute each asana. When these 18 kriyas are integrated in the practice of an asana, the effect is Yogasana. "When the practitioner becomes familiar with these Kriyas and is able to include all the 18 Kriyas in the practice, one can hope for a renewed beginning. It is as if one has rebooted the computer. One then starts Yog practice with some idea and sense of purpose - to make the embodiment a fit instrument to serve our life's purpose." 193 pages.
